The two companies will provide advice to managers of private equity, venture capital, real estate and fund of funds.
The statement also said the new alliance will give Ipes access to US structures and tax complexities which will be especially important when complying with FATCA and other tax exchange agreements.
It added that US fund managers from Los Angeles-based Standish will benefit from access to experts in European fund structures and new European regulatory requirements.

Robert Raynard, managing partner of Standish, said: “Fund managers on both sides of the Atlantic will benefit from the collective knowledge and expertise that our organisations are known for in their respective markets.”
